its not a case of just pressurising it youve got to get the air out too!!!!!!We used a pressure pump like this one http://www.nhbe.net/nsr/gal/Npix/43310_resized_rothenberger.jpg
Remember to use the correct solution which comes with the panels!
Agreed you must leave a filling pump connected and running until all air is out of the system.its not a case of just pressurising it youve got to get the air out too!!!!!!
use a proper solar filling kit.
Dont bother... you can but its one more thing to go wrong just connect your solar fill machine and go and get some lunch..leave it running for a good long while and you shold have no comebacks.question - can you not put auto air vents on the collectors ??
Propylene glycol oxidizes when exposed to air and heat. When this occurs lactic acid is formed.[8][9] If not properly inhibited, this fluid can be very corrosive.[citation needed] Protodin is added to propylene glycol to act as a buffer, preventing low pH attack on the system metals. It forms a protective skin inside the tank and pipelines which helps to prevent acid attack that cause corrosion.
Besides cooling system breakdown, biological fouling also occurs. Once bacterial slime starts, the corrosion rate of the system increases. In systems where a glycol solution is maintained on a continuous basis, regular monitoring of freeze protection, pH, specific gravity, inhibitor level, color and biological contamination should be checked routinely.
Propylene glycol should be replaced when it turns reddish in color.

I personally treat it like underfloor heating where i have left the pump running for 5 or 6 hours, it may seem excessive but i never have any callbacks or complaints.
use a standard hand pump to fill your solar, you dont need anything fancy nor expensive to do it, if its full, pressurised and without air then whats the problem and that comes from myself whos fitted a number of them without issues and also carries a qualification in solar installation.
